TAMPA, Florida (AP) - Busch Gardens says one of its gorillas has delivered a stillborn baby.

The park in Tampa announced Monday that Pele delivered the baby Sunday night.

The park's Facebook page announced in November that Pele, an 11-year-old lowland gorilla, was expecting her first baby late December. The cause of the stillbirth was not immediately known.

Park officials said in a statement that zoo veterinarians and staff are still investigating the cause of death. They said Pele has no apparent signs of complications, but is still under close observation by the veterinary and animal care teams at Busch Gardens.
